Released on August 4th, 2016.

New Features

New Additions to the Dashboard Toolbox: We’ve expanded the dashboard toolbox with some new features and widgets:

Reset Dashboard – this widget can be placed anywhere on a dashboard and allows you to reset any search filters
Browser Detection - this makes light work of testing your dashboard with different web browsers
Click Capture – capture the clicks on your timeline and word-cloud widgets and handle them in your own JavaScript code
Query Edit - Change the query behind a widget on the fly
Widget Property Page Visibility - the property pages of widgets are now exposed via the custom widget API so you modify them programmatically
Modifier Key Handling - We reintroduced this to Facet Tables give you more control in your code

Data Loading Performance: Expect more when loading data – you can now split the search index to allow separate indices for reading and writing.

Improvements

Type Ahead Update: The search type-ahead suggestions are now cleaner and easier to read and indicate how many results match each suggestion
Indexing Performance Tuning: Explicitly identify which fields you want to analyse for type-ahead, alphabetical sorting and searchability
Operator Override: you can create new projects while the Elasticsearch cluster is in 'yellow' state (if you explicitly enable this behaviour in the Squirro configuration). With great power comes great responsibility...
Elasticsearch Default: Squirro now defaults to use the 'elasticsearch' user to run Elasticsearch instead of the 'elastic' user. This conforms to the 'norm' when working with Elasticsearch
Cluster Transparency: the cluster service now provides the _internal/status resource allowing you to query its state and we added the status of MySQL and Redis so it’s easier to get an overview of the cluster state.
Migration Resilience: We improved the MySQL cluster node migration process to make it more resilient to specific error conditions.
Self-Repair MySQL: We also added monitoring and self-repair in case MySQL replication breaks or the MySQL process stops

Bug Fixes

Fixed: Sort gets reversed when editing bookmarks, after query #13, on IE11
Fixed: IE11/IE10 Compatability: Focus is not released from search bar
Fixed: Custom Facet Table headers lose sorting indicators

Fresh Installation Instructions

Please follow the regular installation steps.

Upgrade Instructions

To upgrade to version 2.4.3 of Squirro, please ensure that your current version is at least version 2.3.2 or higher. This is because this version contains a new major version of ElasticSearch. If you are on a version older than 2.3.2, please contact support.

Additionally if you are using Squirro in a Box, additional steps are involved. In this case we also ask you to contact support.

From versions 2.4.x, 2.3.2 or 2.3.3
